Referring to the drawings the numeral I designates a hollow, cast-metalstandard designed to be mounted upon a suitable supp ort for instance abench. Resting on the top of this hollow standard is a base plate 2(Fig. 3) on which is mounted the frame 3 which supports most of theopera! tive instrumentalities and which'provides bearings at5 and 6 forthe substantially horizontal main shaft 4. The bearings 5 and 6 areprovided in the main part of the frame.3, while a forward bearing 1 isprovided. in a forward portion 8 of the frame which projects out beyondand overhangs the forward surface I of the support I so as to exposetheIasting. instrumentalities in convenient position foruse andsojthatmanipulation of the shoe while being lastedwill not beinterferedwith by contact with the support l.

Loosely mounted on the rear end of the shaft 4 is a drive pulley 9 whichmay be coupled, at .will, to the shaft by means of a clutch 10.. Thisclutch may be of any conventional type and need not be described indetail, butisffurnished with an actuating lever .ll (Fig.2) which. isconnected by a rod [2 to a treadle not shown by means of which theoperatoris enabled to actuate the clutch and thus couple-thepulleyil tothe shaft 4. A belt I3 (Fig. 2) embraces a pulley 9 and. also a pulleyI4 on the shaft of a drive motor l5 mounted within the hollow support I.

The shaft 4 (Fig. 3) is provided at its forward part with a, worm 16which constantly meshes with a worm wheel I! fixed to theupper end of avertical shaft 18 mounted. in hearings in the frame member 8 andwhich'is provided with-a pinion 19, preferably of the helical toothtype, which constantlymeshes with a, complemental pinion 20 fixed to theupper end of a. vertical shaft 2| also having bearings in the mainframepart 8 and which is provided at itslower end with a lasting roll.22, hereshown as provided with a helical rib. A complemental lastingroll 23,- preferably of somewhat smaller diameter than the roll 22, isfixed to the lower end of the vertical shaft 24 provided at itsupper endwith a worm. wheel 25 which constantly meshes with the worm IS. Theshaft 24 is mounted to turn in bearings. in a horizontally movable slidemember 26 (Figs.

wardly by means ofa spring 2,] whereby. the forerally projecting pin 28which is engaged by a forked lever 29 fixed to a shaft 30 to which isfixed a lever arm 3| pivotally connected to a rod 32 extendingdownwardly to a treadle (not shown) the arrangement being such that whenthe treadle is depressed the shaft 30 is rocked thereby moving the slide26 forwardly so as to separate the lasting rolls 23 and 22 to permitready introduction of the margin of the shoe upper between them.

Immediatel below the lower end of the roll 23 there is arranged a rigidwork rest and anvil 34 carried by a, vertically adjustable bracket 35sup ported by the slide member 26. This work rest 34 is designed toengage the surface of the insole of theshoe-being lasted, thereby tooppose the upward. pull of the lasting rolls and thus insure the properstretching of the upper material about the last, and also, in thisinstance, to form a rigid abutment or anvil against which the ends ofthe fasteners are clenched.

The mechanism as thus far described is in general substantiallyidentical with that disclosed in the patent to Kamborian No. 2,251,285dated August 5, 1941 and functions in lasting the shoe substantially inthe same way as the corresponding parts of the machine of said patent.

The staple forming and driving instrumentalities and the means foractuating them are for the most part supported by or housed within thecasing 36 (Figs. 2, 3, 4, '7, 8 and 9) which is secured to the underside of the plate 2. This casing 35 is preferably a rigid hollow castingof generally circular form except that it has a forwardly projectingelongate nosemember 31 (Fig. 4) symmetrically disposed with respect tothe vertical plane of the axes of the shafts 2| and 24. This nose member(Figs. '7, 8, 9 and 13) comprises spaced parallel guides 31*- and 31respectively, having finished parallel inner surfaces in whichreciprocates a head 49*- (hereinafter described) constituting a supportfor the forming and driving instrumentalities. The casing 36 is providedwith a hollow boss 38 (Fig. 4) at its bottom which holds a bearing 39for a vertical shaft 40 which has a second bearing in the frame member3, and which is provided at its upper end with a worm wheel 4| (Fig. 3)which is always in mesh with a worm 42 on the shaft 4. Mounted on theshaft 40, within the lower part of the casing 36, is an eccentric 43(Figs. 8 and 10) having a strap 44. Above this eccentric there is fixedto the shaft-a cam disk 45 (Figs. 4 and 9) having a cam groove 46 in itsupper surface; a cam groove 4'!- 13) in the inner surfaces of .theguidemembers 3'! and 33 Thexhead .49'i3is preferably furnished with anupwardly sloping beveled forward surface 52 and has a recess in itsupper surface for the reception of the staple-forming block 53 i(Figsll, 13, 14 and 2'7). which is secured in the slot by rivets 54.1This block 53 has a verticallynarrow front face 55liaving therein atransverse roove 56 of such dimensions as to accommodate (with a snugsliding fit) the wire from which the staples are to be -formed.-- Theblock 53 is provided with a longitudinalsubstantially cruciform guideslot 5'! in its upper face whose side Walls have the parallel guidegrooves 58. Within this slot 51 the staple driver 58 (Figs; 19 and 28)"is arranged to slide, this driver having lateral ribs 60 which arereceived within the slots 58. The forward end (Fig. 28) of thestaple-driving head 59 is preferably beveled at top and bottom at BI andpreferably has a groove 62 at its forward end to receive thestaple-forming wire.

The rear end of the staple driver 59 is pivotally secured (Fig. 8) by apin 59 (Fig. to an actuating slide 63 arranged to reciprocate in guides64 (Fig. 8) forming a part of the case 36. The slide 63 is constantlyurged forwardly by springs 65 secured at their rear ends to brackets 66attached to the slide, and which at their forward ends are secured tolugs projecting from the members 31 and 37 respectively. At its rear endthe slide 63 is provided with a roll 51 (Figs. 4 and 8) which engagesthe cam groove 41 in the under side of the cam disk 45.

The members 31 and 38 (Fig. 8) are provided at their forward ends withparts 3! and 31 respectively constituting vertical guides for avertica'lly reciprocable staple-bending block 68 (Figs. 7, 8, 11 and13). This block or former (Figs. 11, 16, 22, 23) is provided at itsunder side with a pair of spaced downwardly directed forming lugs 69 and70, respectively, the adjacent surfaces of which are spaced apart adistance substantially equal to the diameter of the wire from which thestaples are to b formed. A lug 68 (Figs. 4 and 9) projects from the rearsurface of the block or former 88 and is provided with a pivot pin H(Fig. 4) which enters a slot in the forward end of a lever 12 pivoted atl3 on a shaft l3 extending from the member 3*! to the member 31*. Thislever 12 is provided at its rear end with rolls M which engage theperipheral rib 48 on the cam disk 45.

Fixed in an opening in the member 31 (Fig. 13) is a tubular wire guide15 whose inner or right-hand end is arranged for sliding contact withthe left-hand vertical surface of the forming member 53 as the latteradvances. This tubular wire guide has a bore 16 which is such as toconfine the wire snugly although permitting it to be advanced throughthe guide and across the path of the staple former 53. Connected to andin alignment with the outer or left-hand end of the tube 75 is a rigidconduit 17 which leads to the wire feeding block 58 (Figs. 5 and 24)mounted on the plate 2 at the left-hand side of the machine} This block18 (Fig. 24) has a substantially horizontal guide surface 19 on whichslides the feed block 82 having a horizontal ledge 82 upon which thewire 80 rests as it is fed forward. A swinging retaining pawl 8| urgedto the right (Fig. 24) by a light-spring 8W is arranged to engage thewire and to prevent its rearward movement. The feed block 82 carries oneor more swinging feed pawls 83 and 84 arranged to engage the wire on theforward movement of the feed block 82 and to advance the wire apredetermined distance for each forward movement of the block 82. Thefeed block 82 is-provided with a tail member 85 provided with a pin 86(Fig. 5) which is received in a slot in the end of a lever B! pivoted at88 in the frame 3, and having a pin 89 at its opposite end which extendsthrough a slot 93 (Figs. 5 and 6) in the plate 2 and which engages thecam groove 46 in the upper surface of the cam disk 45. A bracket 9|(Fig. 24) is secured to the face of the feed block 18 and is furnishedat its free end with a guide loop 92 for the wire 89. A tensioning roll93 (Fig. 5) is mounted on a lever 94 pivoted at 95 in the plate 2, andwhich is so urged by a spring t'5 as to maintain the wire under tension.The wire is supplied from a reel 96 mounted on a pivot 91 carried by theplate 2.

The operation of the machine is substantially as follows, it beingunderstood that the motor l5 has been started and that the operator hasactuated the treadle so as to cause the clutch ill to connect the pulley9 to the shaft 5. The shaft 4 is thus rotating and by means of the wormI6 is rotating the shafts 2i and 24, and by means of the worm 42 isrotating the shaft All together with the eccentric 43 and the cam disk45.

The operator actuates the treadle which moves the slide 25 forwardly,thereby separating the lasting rolls 22 and 23 so as to permit themargin of the upper to be introduced between the rolls. The slide 26 isthen released so that the spring 21 moves the roll 23 rearwardly andthus grips the upper material between the rolls. The rolls, with theiroppositely pitched helical ribs, immediately exert an upward drawingaction upon the marginal material of the upper so as to draw the uppersnugly around the last, upward movement of the last being resisted bythe support 35. During this updrawing operation the eccentric 43 and thedisk 45 are turning thus rapidly reciprocating the head 19 with theforming block 53, and also reciprocating the staple driving head 59 andmoving the block 58 up and down in timed relation to the other parts. Itwill be assumed that the head 29 and the forming block 53 are in therearward position as shown in Fig. 14. The feed block 82 is actuated bythe cam groove 45 of the disk 45 so as to advance the wire 89 and topush its end 89 (Fig. 14) out from the end of the tube 15 a distancewhich provides a length 83' (Fig. 14) sufficient to form a staple.Immediatelythereafter, the head 49 and block 53 begin to advance untilthe groove 56 in the forward end of the block 53 embraces the projectinglength 83 of a wire. Further advance of the head 53 causes the lefthandsurface of the head 53 to pass the righthand end of the tube 75, insliding contact, thus shearing off the length of wire which remains inthe groove 53, as an embryo staple S (Fi 15). Immediately thereafter theformer 68 is moved downwardly so that the forming lugs 69 and 10 aredisposed at opposite sides of the wire at the central part of the lengthS. Since the former 68 has no forward motion, the central part of thewire is thus held stationary, and as the forming head 53 continues toadvance, the wire is sharply bent so as to form the parallel legs S andS (Fig. 16) which are disposed Within the grooves 58 of the head 53,these legs S and S being united by the transverse rear portion to form aU-shaped staple. The former 53 immediately rises, thus releasing thestaple to permit its forward movement with the head 53. The head 53continues to advance with the completed staple in its forward end untilthe forward end of the member 53 comes into contact (Fig. 25) with thetensioned upper material at a point just above the upper surface of thefeather of the insole. The final advance of the head 53 acts to wipe-inthe tensioned material over the edge of the insole, and to press itfirmly against the insole rib R, the head 53 thus functioning like thereciprocating wiper of the aforementioned Kamborian patent. At thisinstant the staple driver 59 is advanced relatively to the head 53(which now remains momentarily stationary in its most advanced position,with the forward staple housed in the cavity in its forward end) the camdriver 59 engaging the closed rear end of the staple by its surface 62and thus forcing. the staple out 'of the cavity in the wiper 53 andthrough themarginal material of the upper and into the substanceof therib R, the rib being supported :during the staple-driving action byengagement of its inner surface with the edge of the work rest 34. Thedriving motion of driver 59 is produced by the springs 55, and isin'the'nature of a sudden blow,'the cam groove 4'! having a radialportion 41 (Fig. 9) which permits the sudden release of the roll 6'! andthe instantaneous advance of the drivers. If the staple be long enoughto extend entirely through the rib, its ends will contact the edge ofthe support 34 and thus be clenched, the part constituting an anvil forthis purpose. As roan. as the staple has been driven, the driver head 59is retracted and the forming head and wiper 53 is likewise retractedready for the begining of the next cycle of operations. It may be notedthat during the driving operation the legs S and S are confined in theslots 58 of head 53 whose end is pressed firmly against the Work, sothatduring driving the staple legs are constrained to advance inparallel lines. Thus the staple may be driven into very hard densesubstances without distortion. The operator moves the shoe so that thelasting rolls 22 and 23 progress relatively to th'e sh'oe about theperiphery of the last bottom, exerting constant pull on the upper, whosepoint of application normally shifts by infinitesimal amounts, thelasting operation being a continuous one so long as the operator keepsthe shoe in the operating position. The staples are formed and drivenone for each revolution of the shaft 43, In the preferred embodiment ofthe machine, the rate of staple driving is approximately 175 staples perminute, the ratio of rotation of the shaft 4i: to that of the roll shaft24 being approximately four to one. However, it is contemplated thatother speeds of staple-forming and driving may be desired for certaintypes of work, and the invention is not limited to any particular speedexcept that the speed of driving should be sufficient to insure a properwiping-in of the upper material by the head 53 as the material isreleased by the lasting rolls, and to insure its proper anchorage by thefasteners to the rib of the insole.

While one desirable embodiment of the invention has been illustrated byway of example, it is to he understood that the invention is broadlyinclusive of any and all modifications falling within the scope of theappended claims, and

that while the machine is primarily designed for lasting welt-typeshoes, it may, if merely by modification' within the scope of theclaims, he employed for stressing and inserting fasteners in flexiblematerial other than shoe uppers.
